'Arms' in the Bible

Then the Ammonites were called to arms, and they encamped in Gilead; and the people of Israel came together, and they encamped at Mizpah.

The men of E'phraim were called to arms, and they crossed to Zaphon and said to Jephthah, "Why did you cross over to fight against the Ammonites, and did not call us to go with you? We will burn your house over you with fire."

When he came to Lehi, the Philistines came shouting to meet him; and the Spirit of the LORD came mightily upon him, and the ropes which were on his arms became as flax that has caught fire, and his bonds melted off his hands.

So Deli'lah took new ropes and bound him with them, and said to him, "The Philistines are upon you, Samson!" And the men lying in wait were in an inner chamber. But he snapped the ropes off his arms like a thread.
